Ruby Clinochlore Meaning, Metaphysical Energy & Geology

A mixed-mineral specimen submitted under a ruby label was tested to identify its red corundum and green host minerals.

Finding: The April 20, 2022 report printed sample 92905 (#5) and found a chlorite-group mineral, likely clinochlore, corundum/ruby, spinel, zircon and a magnesium-rich pyroxene or amphibole. The exact pyroxene/amphibole species was not resolved; anthophyllite was considered a likely fit. Phlogopite was not found in the analyzed areas.

Catalog note: The printed sample ID 92905 is repeated on unrelated beryl and Australian pink-stone reports. This page identifies the April 20 ruby-association specimen by its mineral findings; the reports remain separate.

Understanding the report figures

Use this guide alongside the written findings and the original report transcript. It explains the purpose of each analytical figure and preserves the laboratory’s own figure labels. The interpretations apply to the tested specimen; signals alone do not establish the identity of every similar-looking stone.

Electron microscope image: This view shows small-scale regions selected for analysis. Its brightness contrast helps distinguish regions with different compositions; it is not a photograph of their natural colors. Numbered spots connect this view to the analyses listed in the report.
Laboratory figure caption: Fig. 2: Backscattered electron image of an area of the specimen.
Elemental spectrum: The peaks record characteristic X-ray signals from elements in the analyzed spot or area. This is an analysis of that location, not automatically of the entire specimen. Any mineral identification or uncertainty named in the laboratory caption is retained below.

Summary of findings: This specimen (Fig. 1) is very interesting! It is composed of a number of mineral species: a chlorite group member, likely clinochlore (Figs. 2 and 4), spinel (Figs. 5 and 8), corundum (Figs. 5 and 7), a magnesium-rich pyroxene or amphibole (enstatite or anthophyllite) (Figs. 2 and 4), the presence of aluminum indicates possibly anthophyllite would be the best fit, and minor zircon. (Figs. 5 and 6). The whole assemblage is highly aluminum and magnesium enriched and suggests a source in a metamorphic environment with a protolith of mixed pelitic , ultramafic or possibly carbonate rocks. Under these conditions, phlogopite would be an expected mineral but it was not found in the areas investigated.
